Specification forming part of Letters Patent No. 122,231, dated December26, 1871.

SPECIFICATION.

Be it known'that I, JosEPH W. OREMIN, of New York, in the county of NewYork and State of New York, have invented a new and ImprovedWater-Meter; and I do hereby declare the following to be a full, clear,and exact description of the same, reference being had tothe'accompanying drawing making a part of this specification, in which-Figure 1 is a vertical sectional view of my improved water-meter. Fig. 2is a perspective view of the arms and the mechanism immediatelyconnected therewith. Fig. 3 is'a top view of the meter. Fig. 4 is aninside view of the upper half of the case, and Fig. 5 is an exteriorview of the bottom of the meter.

This invention relates to the application of the device known as Barkerscentrifugal mill to a water'meter, the revolving arms being placedwithin a case and mounted on a hollow shaft extending cross-wisetherein, said shaft connecting at one side of the chamber with thesupply-pipe and at the other side with the registering clockwork, whichis put in motion by the turning of the shaft through the agency of waterrushing into the arms and out at the ports in or near the ends of thelatter, in the ordinary way of operating the centrifugal mill. This isan improvement upon my patent No. 115,937, dated June 13, 1871, forWater-meters; and the invention consists in the improvements hereinafterdescribed and more particularly referred to in the claims. Referring tothe drawing, A is the case, composed of two pieces or sections, whichare connected by means of a screw-thread cut on each at g, the lowerpart resting on the legs I l l. D is the hollow shaft connecting thehollow arms 0 G, and having at its upper end a short hollow extension,01, which fits loosely into a water-bearing, d formed in the case A forits reception. The shaft D, at its lower end, fits loosely, also, into awater-bearing formed within the lower part of the case, the waterentering through the small apertures 01 The arms 0 G are made with sharpcutting-edges at 70 k, and with flat vertical sides at h h. In the flatsides, and near the outer ends, are ports a. 0 through which the waterflows that enters the shaft D through the supply-pipe i The ends of thearms are also sharp and rounded, and their cutting-edges enable them toforce their way easily through the water in the case A. To the hollowshaft (1 is rigidly connected a pinion, a which meshes with a gearwheel, 6 placed on a vertical shaft, e. Upon the upper end of this shaftis a pinion, e to which the clock-registering apparatus is to beattached. The flange f surrounds the saidapparatus, over which a coveris placed to protect and inclose the clock-work. line with theoutlet-pipe 0 o is an aperture lead in g from the inside of the meter tothe outlet pipe. at is a screw situated within the shaft D, soconstructed as to assist in rotating the arms by the action of the wateron it. The water enters from the supply-pipe at i, passes up through thehollow shaft D; thence laterally in the arms 0 O, and through the portsa a causing the rotation of the arms and the gearing that connects withthe clock-registering apparatus. The hollow shaft 01 is open also at theupper end, so that the pressure of the water may not force the shaft andits arms against the top or side of the meter, and thereby causeconsiderable friction. Its

being open also subserves another purpose, viz.,

to aid in giving the shaft :1- water-bearing at that end. Theconstruction of the caseA is peculiar, being made so as to inclose inacircular form the water and operating parts in one chamber and theregistering apparatus in another, inthe most compact manner possible. I

My object in constructing this meter has been to produce one that issimple in construction, cheap, durable, safe, (in connection withsteamboilers,) accurate in registering under any pressure, and one thatwill operate under all circumstances. This I have accomplished andproved by repeated tests, and am nowienabled to present to the publicone that possesses all these requisites.

What 1 claim, and desire to secure by Letters Patent of the UnitedStates, is

1. The combination of the hollow arms 0 O, shaft D, extension 01, andthe screw a.

2. The combination of the arm 0 o, Shaft D,

extension 01, screw a, pinion a gear-wheel a, shaft 6, pinion c and caseA, as and for the purpose set forth.

3. The case A A, constructed internally and externally as described andshown, and in two parts, one having on the exterior the flange f and theother the ingress and egress ports.
